The idea of a postpaid plan comparator evolved in my mind when I realised how unaware consumers in general are about the savings that they could achieve on their mobile phone bills if they are willing to make the most cost effective decision.
The comparator takes into consideration about 25 different postpaid plans offered by mobile operators such as Airtel, Vodafone, Idea, Aircel, Reliance Communications and MTS. In the beta version only plans which have pay per minute billing have been considered which is why Docomo is conspicuously absent in the Comparator.
The beta version also assumes a certain standard split between the onnet and offent usages. Please feel free to download the comparator in excel and tinker around to suit your specific usage pattern.
In disclaimer I would like to say that this is an honest effort with no operator bias to make the consumer more aware. Please point to me any mistakes that I might have made in calculation, depictions, rates considered etc. All tariff details have been obtained by either calling up the customer care desks or from the website of the respective companies and are up to date as of May 2012. The Tariffs considered in the beta release are of plans available in Karnataka. For specific information and availability of a plan please contact the customer care desk of the operator.
